Create First Program with Ruby in ubuntu

1.) Open terminal by pressing Ctrl + Alt + T and write command like this:
      – emacs -nw helloworld.rb
      – In ruby file extension must be .rb so here we give the name as helloworld rb , helloworld is a file name            and .rb is extension

2.) And write code here in helloworld.rb:
     puts “Hello World”

3.) Save file by pressing Ctrl + x + s

4.) Exit from editor by pressing Ctrl + x + c

5.) Now how to execute our first program so for that you want to write like this syntax :
     – ruby filename.rb
     – ex : ruby hellowolrd.rb

     – in our case result should be like this

Hello World
